trying again

so ladies I have a question... I had a miscarriage at 4 weeks and 4 days. (technically it was only 2) but I didnt need a D&C; or anything... how long should I wait to try again? it's been about 2 weeks since I miscarried and my boyfriend travels for work so its hard to meet ovulation dates hes been off work but goes back in a few weeks like right before I ovulate I'm still sad about my angel baby but I just dont know when is a safe time to try again
